This invention relates to flue or tube beating tool and has for its objects to provide a comparatively simple, inexpensive device of' V this character which may be readily operated by an unskilled person, and one which in practice will efl'ectuall beat thetubes after they have been expan ed in the usual 1nanner, the beating being accomplished more readily and quickly thanwith an ordinary beating tool. I l

With these and other'objects in view, the

is a perspective view of a flue beater embodying the invention. Fig. 2 .is a view partly in section, the section being taken centrally and longitudinally through the tool head.

The tool is preferably a for ing of tool steel and tempered and is formed on the outer edge at a point near its rear end with a projecting portion 6 having a semi-' circular undercut heating or forming surface 7. Formed in theinner edge of the tool adjacent its forward end is a socket 8 in which is seated-one. end of a compression spring 9 havin its other end seated in a socket 10 forme in the head 2 at the bottom of the re- :shank having a hea tudina'l laterally o ening slot, a tool mov- -in presence of two witnesses.
